Vue通过状态为页面切换添加loading、为ajax加载添加loading

以下方法需要引入vuex,另使用了vux的UI框架,ajax添加loading还引入了axios。

 

一、为页面切换添加loading。

  loading.js:

import Vue from 'vue'
import Vuex from 'vuex'
import router from './router'

Vue.use(Vuex)

const store = new Vuex.Store({}) // 这里你可能已经有其他 module

store.registerModule('myVux', { // 名字自己定义
  state: {
    isLoading: false
  },
  mutations: {
    updateLoadingStatus (state, payload) {
      state.isLoading = payload.isLoading
    }
  }
})
router.beforeEach(function (to, from, next) {
  store.commit('updateLoadingStatus', {isLoading: true})
  next()
})

router.afterEach(function (to) {
  store.commit('updateLoadingStatus', {isLoading: false})
})

export default store;

  main.js

import Vue from 'vue'
import Vuex from 'vuex'
import App from './App'
import router from './router'
import store from './loading'

Vue.use(Vuex)
Vue.use(router)

new Vue({
  el: '#app',
  router,
  store,
  template: '<App/>',
  components: {
    App
  }
})

  App.vue:

//在模板中加入以下vux组件
<loading :text="loadText" v-model="isLoading"></loading>


  import { Loading } from 'vux'
  import { mapState } from 'vuex'

  export default {
    name: 'app',
    data(){
      return {
        loadText:"loading"
      }
    },
    components: {
      Loading
    },
    computed:{
      ...mapState({
        isLoading: state => state.myVux.isLoading
      })
    }
  }

 

 

二、为ajax添加loading(发送请求时显示,返回数据时消失)。

  loading.js:

import Vue from 'vue'
import Vuex from 'vuex'

import Axios from 'axios'
 Vue.use(Vuex)

Axios.interceptors.request.use(config => {
console.log('ajax begin request')
store.commit('ajaxStar')
return config;
})

Axios.interceptors.response.use(config => {
console.log('ajax get response')
store.commit('ajaxEnd')
return config
})
store.registerModule('myVux', { // 名字自己定义
state: {
ajaxIsLoading: false
},
mutations: {
ajaxStar (state) {
state.ajaxIsLoading = true
},
ajaxEnd (state) {
state.ajaxIsLoading = false
}
},
getter : {
ajaxIsLoading: state => state.ajaxIsLoading
}
})
export default store;

  main.js

import Vue from 'vue'
import Vuex from 'vuex'
import App from './App'
import router from './router'
import store from './loading'

Vue.use(Vuex)
Vue.use(router)

new Vue({
  el: '#app',
  router,
  store,
  template: '<App/>',
  components: {
    App
  }
})

  App.vue:

//在模板中加入以下vux组件
<loading :text="loadText" v-model="ajaxIsLoading"></loading>


  import { Loading } from 'vux'
  import { mapState } from 'vuex'

  export default {
    name: 'app',
    data(){
      return {
        loadText:"loading"
      }
    },
    components: {
      Loading
    },
    computed:{
      ...mapState({
    ajaxIsLoading: state => state.myVux.ajaxIsLoading

}) } }
